Abstract

Objective:To study the polar chemical constituents of Blettila striata(Thunb.) Reichb.f. Methods:The constituents in N-butanol moiety were separated and purified by column chromatography with silica gel and SephadexLH-20, and were identified by spectral analysis. Results:Five compounds were identified as: militarine(1);7-hydroxy-4-methoxy-phenanthrene-2-O-β-D-glucoside(2);4-methoxyphenanthrene-2,7-O-β-D-diglucoside(3);7-hydroxy-2,4-dimethoxyphenanthrene-3-O-glucoside(4);3′-hydroxy-5-methoxybibenzyl-3-O-β-glucopyranoside(5). Conclusion:Compound 1,5 were isolated from this plant for the first time.
